Running e(fx)clipse on OpenJDK 11. WAS: Running Eclipse on OpenJDK 11

Question

I had Eclipse Oxygen running on Oracle's JDK 8 and that worked fine. Today I've updated my Eclipse install to the latest version, and it still worked fine.

Then I installed OpenJDK 11 and JavaFX 11, and uninstalled Oracle's JDK I previously had. Now Eclipse won't start. I paste the last session recorded in the .log file below.

Does Eclipse 2018-12 run on Open JDK 11? How can I do that? The Eclipse web site does not seem to mention Open JDK 11 at all.

Update: looking more closely at the .log file it seems Eclipse is missing JavaFX. I installed JavaFX 11, including creating the environment variable PATH_TO_FX per JavaFX installation instructions. Any ideas of what may be wrong?

Answer 1

By looking more closely at the log file I suspected the e(fx)clipse plugin was causing the problem:

at org.eclipse.fx.osgi.fxloader.FXClassLoader.createModuleLoader(FXClassLoader.java:177)

And indeed, I found this thread on the e(fx)clipse forum with a similar report, and an answer by one of the developers that this was a bug on version 3.3.0 and that they would try to release 3.5.0 as soon as possible which had a fix. However, it seems that has not happened as of today.

So I reverted to JDK 8, uninstalled the e(fx)clipse, and now my Eclipse install works with OpenJDK 11.
